Hi devs,

On my kind=type branch (D808), I have this test failure for stranal/sigs/UnsatFun:

Hmmm. I was curious and so took the opportunity to do a bit of digging. This likely isn't helpful but you never know...

-UnsatFun.g: b +UnsatFun.g:

It looks like the strictness analyzer can no longer see that `g` is bottoming (hence the missing `b`), which unfortunately seems to be exactly what this test is testing for. :( Moreover, the `B` changing to an `L` means that the demand analysis can't see that any demand is made of the first argument.

-UnsatFun.h: +UnsatFun.h:

This is the helper used by `g`. Again, it looks like something is going awry here with strictness analysis as the argument which was previously deemed "call-demand" is now just "strict".

-UnsatFun.g': +UnsatFun.g':

-UnsatFun.h2: +UnsatFun.h2:

This appears to be a very similar test which is likely failing for a similar reason. Could you perhaps collect the Core for this test before and after your patch?
